I need a layman's term definition of these parameters and what they do in terms of allocating resources to servers, as I'm having issues with the VPS's that I set up, as Java seems to be unable to set up a virtual machine on them for minecraft unless they have over 2Gb's of each parameter, and I'm assuming I must be doing something wrong. Here is the current script exert that I use to initially create the server and assign resources:

SERVID=$1
IPPICK=$2
HOSTNAME=$3
PW=$4
EMAIL=$5

if vzctl create $SERVID --ostemplate centos-6-x86_64.2 --config vps.packtwo-basic ;
    then
        echo -e "\nVPS container was successfully created...\n"
    else
        vzctl stop $SERVID
        vzctl destroy $SERVID
        echo -e "Please restart the package install, there was a problem creating the VPS..."
        exit $?
fi
if vzctl set $SERVID --onboot yes --save;
    then
        echo -e "\nSet to boot on start...\n"
    else
        vzctl stop $SERVID
        vzctl destroy $SERVID
        echo -e "\nPlease restart the package install, the onboot config went wrong...\n"
        exit $?
fi

if vzctl set $SERVID --ipadd $IPPICK --save;
    then
        echo -e "\nIP added to the VPS successfully...\n"
    else
        echo -e "\nThe IP address used, may be used on another server, this may mean that the server has an issue contacting external addresses..\n"
fi

if vzctl set $SERVID --hostname $HOSTNAME --save;
    then
        echo -e "\nHostname assigned to the VPS successfully...\n"
    else
        vzctl stop $SERVID
        vzctl destroy $SERVID
        echo -e "\nPlease restart the package install, there was a problem assigning the Hostname to the VPS...\n"
        exit $?

        then

        else

        vzctl destroy $SERVID
        echo -e "\nPlease restart the package install, there was a problem assigning the chosen password for the root account...\n"
        exit $?

The minecraft server fails to start with less ram because by default the -Xmx and -Xms settings in the run.sh are 2GB or higher. –  jordanm Jan 24 '13 at 20:40
    
No they're not, they're set to 1024Mb's. It's not a standard minecraft server I'm running, it's a minecraft server with a panel. All of it, is set to the correct resources and such. –  Conner Stephen McCabe Jan 24 '13 at 20:50
    
Do yourself a favor and don't run Java applications such as Minecraft on OpenVZ. Even if you get past this hurdle, the performance is going to be terrible. –  Michael Hampton Jan 25 '13 at 0:40
    
Well, I currently have one running and the performance is terrific, so you clearly know nothing. –  Conner Stephen McCabe Jan 25 '13 at 2:17
